Auth Service JWT Generation + Validation Tests

[tmthecoder]

Write Tests for Auth Service JWT Generation + Validation

Context

The Auth Service RPC exposes JWT create + validate methods. Create is used in the api gateway and validate is used across services to validate tokens before accessing services. These endpoints need to be testes

Requirements & Criteria

• [ ] Tests are written within auth-service/tests/app.e2e-spec.ts
• [ ] Tests cover cases of invalid input (with appropriate exception/error checking)
• [ ] Tests cover cases of correct input
• [ ] Tests cover all of gRPC methods (createJWT, validateJWT)

NOTE: The full test-suite for any package can be run in the root directory of the project by running yarn test:e2e:[service-name]
